In a large saucepan, heat the oil over a medium heat. Add the onion and garlic and sauté for about 5 minutes, or until the onion is translucent.

Add the bell pepper, jalapeno (if using), sweet potato, and tomatoes with their juices. Raise the heat to medium-high and simmer for 5 minutes more. Season the vegetables with salt and black pepper.

In a medium bowl, whisk together the peanut butter and 250ml of the vegetable broth until no clumps remain. Stir the mixture into the vegetables along with the remaining 750ml broth, chilli powder, and the cayenne (if using).

Cover the pan with a lid and reduce the heat to medium-low. Simmer for 10 to 20 minutes, or until the sweet potato is fork-tender.

Stir in the chickpeas and spinach and cook until the spinach is wilted. Season with salt and black pepper to taste.

Ladle the stew into bowls and garnish with coriander or parsley and roasted peanuts.

Tip:

Have some leftover cooked rice? This soup is fabulous with some stirred in.
